Question

The high temperature on Friday was 8 degrees above zero. The low temperature was 3 degrees below zero. Which expression gives the average of the low and high temperatures?
Negative (3 + 8) divided by 2
(negative 3 + 8) divided by 2
(negative 3 + 8) divided by (negative 2)
Left-bracket negative 3 + (negative 8) right-bracket divided by (2) Right-bracket

Answer 1

Using the mean concept, the expression that gives the average of the low and high temperatures is:

(-3 + 8)/2.

What is the mean?

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In this problem, the two observations are -3 and 8, hence their average is given by:

(-3 + 8)/2.
